After the shocking 24-13 defeat at the hands of the Indianapolis Colts in Sunday’s Divisional playoff game, Denver Broncos head coach John Fox has parted ways with the organization.

Fox went 46-18 in four season with Denver, which amounts to a whopping winning percentage of 71.8. Yet despite the regular season success the past four years, Fox has a lifetime playoff record of 3-4 dating back to his time with the Carolina Panthers, where he spent nine years as head coach.

The mutual departure comes as quite a shock to league insiders, especially since GM and Executive Vice President of Football Operations John Elway said in last night’s post-game interview that Fox would be back next season. However, even before the game with the Colts, there had been rumors around the league that Fox could be out in Denver if he failed to advance past the Divisional round.

It is unclear whether the move is directly related to the uncertain futures of both quarterback Peyton Manning and Offensive Coordinator Adam Gase. The latter has been interviewing with other teams as a prime head-coaching candidate for several weeks now. Five clubs, including the Atlanta Falcons, Oakland Raiders, San Francisco 49ers, Chicago Bears and Buffalo Bills, all have current head-coaching vacancies. John Fox will now likely be interviewing along with Gase for one of these vacancies.

Manning on the other hand, at 38 years old, coming off four neck surgeries and now a reportedly compromised quad injury sustained in recent weeks, is no sure thing to return to Denver next year either. Perhaps overwrought with emotions of a season finale, a disappointing one at that, Manning was noncommittal in his post-game press conference last night.

In three years as the Bronco’s starting QB, Manning has posted a regular season record of 38-10. He set many team and individual passing records in 2013 en route to a 43-8 Super Bowl loss to the Seattle Seahawks last February. With the loss yesterday to the Colts, Manning now has a 2-3 post-season record with the Broncos. For his career, he is 11-13 in the playoffs, including a historical nine first round exits.

Adding to the mystery regarding Manning’s future, a report came out last night from Broncos officials that the Hall of Fame QB had been severely hampered by a quad injury over the past few weeks. Whether this truly accounts for Manning’s steep decline over the month December, or if it is just a product of aging and inclement weather, remains to be seen. Manning is under contract next year for the Broncos, scheduled to get paid around $20 million for his services.

If Gase is not promoted from within and indeed opts to coach for another team next year, the move would likely necessitate an entirely new offensive system for Manning to learn, shall he himself return. This could also be a major influencing factor regarding Manning’s decision to play for season number 18.

Many questions loom for what has been a premiere team in the AFC the last three seasons. At this time, the team is without a head coach, and could soon be without both its starting hall of fame QB and wunderkind offensive coordinator.
